As for the plot, Winger says it was the brainchild of his partner Damien Gray, who wanted to write a musical centered around the victims of the notorious serial killer Jack the Ripper.

"We call it a musical thriller because it's sung-through, like Les Mes, so it's not a typical musical. It's almost like an opera, but it's kind of falling in-between."

He says the cast includes five lead women singers and three men.

"We really immortalize the women in this. They go back to get vengeance on Jack, and the Devil wants his soul. We're really happy with it."

Winger says Get Jack is already two-and-a-half-years in the making. The music has been arranged for an orchestra and a rock band.

"I'll be doing the orchestra in Prague in January," he says. "It was thrilling for me, because I've written several symphonic works, but now I've added vocals to it, which didn't even dawn on me to be honest with you.

"Like, 'Wait a minute. I've been writing songs.' So writing for singers came totally naturally."
